To all whom it may concern: 1

Be it known that I, JOHN F. OCoN-NoR, a citizen of the United States, residing at 7 Chicago, in the county of Cook and State of Illinois, have invented a certain I new and useful Improvement in Draft-Rigging, of which the following is a'full, clear, concise, and exact description, referencebeing had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements'in draft riggings. 1

One object of the invention is to provide a detachabledraw bar and yoke connection wherein is employed a standard shouldered draw'bar and the use. of a coupler'key is eliminated.

Another object of the invention is to provide a draft rigging wherein is employed a draw bar and yoke having a detachable connection, the detachable connection between the draw bar and yoke being so arranged that the parts are held in assembled relation by the stop members of the draft rigging.

In the drawing forming a part of this specification, Figure 1 is a longitudinal vertical section of a draft rigging showing my improvements in connection therewith. Fig. 2 is a horizontal sectional view taken substantially on the line 22 of Fig. 1. Fig. 3 is a vertical, transverse sectional view taken substantially on the line 33 of Fig. 1. And Figs. 4 and 5 are detail perspective views illustrating one of the connecting blocks and yoke. respectively.

In said drawing, 1010 denote channel shaped center sills of a car underframe between which extend upper and lower, horizontally arranged channels 1111 with their flanges extended upwardly and downwardly, respectively. The channels 11-11 are each provided with a rectangular recess 12 to accommodate the followers 13-13 and a vertical, twin springs Pi -1 1 of a spring gear. The arrangement is such that the followers andsprings can be inserted from below and are held in proper position by a removable saddle plate 15. It will be noted that the webs of the channel stop members are located in line with the axis of the springs to thereby increase the efiiciency of I the stop members in resisting shocks.

The draw bar 16 is of standard type and 1 isproyided with upper and lower shoulders 17-'-'-17 the'butt thereof. Iii-view of the arrangement of stop members, a horizontal yoke 18 is employed,the same comprising a rear connecting portion 19, horizontal side arms 2O 2O,each of the latter being provided at its ,front end with a rectangular enlargement forming upper and lower rear shoulders '21'21 and a front," vertical face 22. The enlargements are preferably hollow except for a vertical web 23 which is provided for strength. The enlargements on the ends of the yoke arms are spaced apart sufficiently to accommodate thebutt of'the draw bar 'therebetween' and, in vertical height, are substantially the same asthe vertical heightof the draw bar butt: To detachably connect the yoke'18 with the draw bar, I have provided a pair of blocks each of which is designated generally by the reference A. As shown, each of said blocks A comprises a horizontally extending plate portion 24, rear, transversely. extending shoulder or flange 25 adapted to engage the rear face'of the draw bar butt and apair of saidv shoulders 21, and a front, transversely extending shoulder. or flange 26 adapted'to engage one of the shoulders 17 of the draw bar and against the front faces 22 oftheenlarged ends of the yoke arms. Where the front shoulder or flange 26 overlaps the ends of the yoke arms, it is extended downwardly, as indicated at 27 at the corners thereof, to thus provide a larger bearing against the yoke ends.

The blocks A are assembled with the yoke and draw bar in the manner shown most clearly in Fig. 1, that is, with one block on the top of the draw bar butt and the other on the bottom thereof, the latter resting on and supported by the'lower stop member 11. It will be noted that the vertical distance between the stop members 11-11 is such as to accommodate the draw bar with the blocks A, A thereon without binding, but in such a manner as to prevent accidental disengagement of said blocks A. .100

The gear is assembled by first connecting the draw bar and, yoke by applying the blocks 'A, A and then inserting these members longitudinally between the stop castings; The gear proper maythen be inserted from below and held in place by applying the saddle plate 15. 7

From the preceding description, it will be seen that I have provided a simple, detachable connection between a standard drm bar and yoke and one which obviates the use of all keys or rivets. 7
